Abstract
X-ray detectors are made by growing CsPbI3 on a treated surface of a conductive layer. Growth is controlled by increasing solvent concentration in the atmosphere in which the growth occurs. Columnar crystals grown in a plurality of wells extend between conductive surfaces at least one of which is pixelated to produce a columnar detector array.
Claims41
A method of growing orthorhombic cesium lead iodide (δ-CsPbI3) microwires, comprising:
- drop-casting a solution of CsI and PbI2 in a solvent onto a patterned substrate;
- and
- forming at least one δ-CsPbI3 microwire by allowing the solvent to evaporate.
An X-ray detector, comprising:
- a first conductor and a second conductor;
- and
- at least one orthorhombic cesium lead iodide (δ-CsPbI3) microwire extending from the first conductor to the second conductor and electrically coupled to the first conductor and the second conductor proximate respective ends of the at least one δ-CsPbI3 microwire.
An X-ray detector, comprising:
- a base substrate;
- an upper substrate;
- and
- a plurality of δ-CsPbI3 microwires extending from the base substrate to the upper substrate.
1 more element
A method, comprising:
- growing δ-CsPbI3 microwires in a plurality of wells so that a first end of each extends to a base conductive layer;
- and
- contacting second ends of each of the δ-CsPbI3 microwires to an upper conductive layer.
